hi everyone, got my 92 f150 with the straight 6 and e4od tranny.....pulled codes today and i got code 327,328, 332, and 634....any help would be greatly appreciated...i know i habve somwething wrong with egr valve? says code book......its been driving good except for hesitating when cold and shifting hard on occasion..replaced the vss and unpluged rabs and its been driving awsome, except for on drives longer than 10 miles, it starts shiftin real hard. but if i turn it off and on again its usually good for another 10 miles or so.......any advice or comments? please help thanks

 

These are your code definitions. Looks like your EGR valve is not opening. I have to hit the streets but will check back this evening. Hopefully you'll get more/better help during the day.


DN90 CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODE (DTC) 328, 327 OR 337: CHECK FOR INTERMITTENT SENSOR
Continuous Memory DTC 328 or 327 indicates the EGR valve was closed further than normal or EVP sensor or circuit has failed with an intermittent low voltage sometime during vehicle operation.

Continuous Memory DTC 337 indicates the EVP signal to the Powertrain Control Module (PCM) was above the maximum Self-Test limit sometime during vehicle operation.

Possible causes:

Poor continuity in EVP harness or connectors.
Intermittent open or short in EVP sensor or harness.
Damaged EVP sensor.
Disconnect Powertrain Control Module (PCM). Inspect for damaged or pushed out pins, corrosion, loose wires, etc. Service as necessary.
Install breakout box, reconnect PCM.
Connect DVOM between Test Pin 27 and Test Pin 46 at the breakout box.
Key on, engine off.
Lightly tap on EVP sensor and wiggle harness connector to simulate road shock.
Note: EVP voltage with EGR valve closed is normally between .24 and .67 volt and steady. A sudden change in voltage indicates a fault.

DN110 CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODE (DTC) 332: CHECK EGR VALVE FUNCTION
Continuous Memory DTC 332 indicates the EGR valve did not open with the engine stabilized and the EVR solenoid duty cycle present sometime during vehicle operation.

Possible causes:

Obstructed or cracked hose to EGR valve.
Damaged EGR valve.
Damaged EVR solenoid harness.
Key off.
Disconnect vacuum hose at EGR valve and connect a hand vacuum pump.
Apply 10-20 in-Hg (34-67 kPa) to EGR valve.

TD1 KEY ON ENGINE OFF DIAGNOSTIC TROUBLE CODES (DTCS) 67/634, 522 AND 654:
CHECK MANUAL LEVER POSITION (MLP) SENSOR ALIGNMENT

DTCs 67 and 634 indicate the MLP sensor is out of Self-Test range when the gear selector is in PARK.

DTCs 522 and 654 indicate the gear selector was not in Park during Self-Test.

Possible causes:

Misadjusted linkage.
Open or short in harness circuits.
Damaged MLP sensor.
Damaged PCM.
Key off.
Apply parking brake.
Place transmission in NEUTRAL.
Verify that Manual Lever Position (MLP) Sensor Tool (Rotunda T91P-7010-AHT) or equivalent fits in the appropriate slot.

 

I had 327, 328, and 332 before, pulled the egr down and it was fairly clean. Checked the signal from the egr position sensor on top of the valve and it jumped huge gaps. New sensor fixed my issue. It was stumbling and falling on its face while driving

 

would any of these codes have anything with my occasional hard shifting issue?

 

With an E4OD any DTC code can and usually does cause hard shifting.. I'm willing to bet that if and when you get the trouble codes cured (not just cleared) your E4OD will be back as it should be..

 

thanks for the replys! when it stops raining im going to check it out, is there anything else i need to know that would be helpfull? im newer to all of this

 

any other imput? iappreciate the responses, just would like as much indo as possible, and maybe a "how to" guide

 

bump bump.....anyone have a how to guide on how to do/check all this stuff......also i noticed when im a a red light my batt gauge drops allot....think i have a short in my brake lights???....brand new alternator couple months ago....help please

 

hello ?????????????

 

Sent you a PM.

 

i cleaned all the connecters and its still doing it.....

 

Did the EGR codes clear? I most definitely am NOT an automatic trans tech! Maybe post this in the Transmission section here?

 

still the same codes are showing up....im at my wits end......maybe i need to clean egr

 

Uh, yeah, maybe. I mis-read Brian129's post as being yours ............ fixing the EGR issue would be a good starting point.

 

can someone show me a pic of where this egr is located?
